Проведено проспективное рандомизированное одноцентровое исследование. В исследование включено 166 пациентов с заболеванием митрального клапана, разделенных на 3 группы в зависимости от длительности фибрилляции предсердий (ФП): с пароксизмальной ФП у 14 (8,4%) пациентов, с персистирующей ФП у 63 (37,9%) пациентов и с длительной персистирующей ФП у 89 (53,6%) пациентов, госпитализированных в Межрегиональный клинико-диагностический центр Казани с 2011 по 2018 г. Средний возраст пациентов составил 57 ± 5 лет, женщин было 97 (58,4%).Результаты. Хирургическая изоляция устьев легочных вены и ЛП с помощью РЧА при замене митрального клапана позволяет восстановить синусовый ритм, что определяет ремоделирование ЛП, таким образом отмечается улучшение транспортной функции левых отделов сердца в целом.</p></abstract><trans-abstract xml:lang="en"><p>Material and methods. A prospective, randomized, single-center study was conducted. It included 166 patients with mitral valve disease divided into three groups depending on types of AF: with paroxysmal AF at 14 (8.4%) patients, with persistent AF at 63 (37, 9%) patients and with long-term persistent AF at 89 (53.6%) patients hospitalized at the Interregional Clinic and Diagnostic Center Kazan from 2011 to 2018. An average age of patients was 57 ± 5 years old, mainly females amounted to 97 (58.4%).Results. Surgical isolation of the pulmonary vein ostia and the left atrium by RFA at mitral valve replacement significantly improves the contractile function of the left atrium, which allows us to judge about the improvement of the transport function of the left heart chambers as a whole.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оценка геометрических параметров функционального и механического ремоделирования&#13;
